I have almost the same behavior with 16.04.3. It doesn't log me out but restarts Unity. Freshly installed 16.04.3 runs normally. After installing updates Unity crashes exactly like in the OP. Same compiz segfault at 0 ip (...) error 4 in i965_dri.so (...) with slightly different addresses.
In low graphics mode it is a bit better but not completely gone. As for hovering over the sidebar, it takes a half a second before Unity crashes, I suspect it happens when it tries to show the tooltip. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1735594 Title: ubuntu automatically logs out when hovering sidebar To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1735594/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
